"Data Services for the Social Sciences" is a department of GESIS - Leibniz Institute for the Social Sciences. Its mission is to foster FAIR data, open science and reproducible research in the quantitative and computational social sciences. To ensure that data holdings remain usable and interpretable over the long term, it offers sustainable infrastructures and services for data management, curation, and long-term preservation. ​These include archiving services with different curation levels for different needs as well as access to archived data including access to sensitive data in the GESIS Secure Data Center. The services also cover the data registration agency da|ra and training on data management for easier retrieval and re-analysis of data.

The Internet Archive is a non-profit organization that offers permanent access for the general public to historical collections that exist in digital format. The Internet Archive includes collections of digitized materials, including websites, software applications and games, music, movies and videos, moving images, and nearly three million public-domain books. The Internet Archive allows the public to upload and download digital material , but most of its data is collected automatically by its web crawlers to preserve as much of the public web as possible. The Wayback Machine, a huge web archive, contains over 150 billion web captures.

SpringerMaterials is based on the Landolt-Börnstein New Series, the unique, fully evaluated data collection in all areas of physical sciences and engineering. It is a systematic and comprehensive resource of selected and critically assessed data explained in their scientific context.

The department "Survey Data Curation", part of GESIS - Leibniz Institute for the Social Sciences, processes and prepares social science research data across a diverse range of data types to support research, especially in comparative perspectives across space and time. The curated data include long-term national (e.g., ALLBUS, GLES, Politbarometer, FReDA) and international (e.g., ISSP, EVS, CSES, Eurobarometer) survey programs with large user communities. The data are prepared for immediate re-use for research and teaching purposes. The department also offers services for linking surveys with geo-data and digital behavioral data.
